Undercut Anchoring System

Designed for 12–20 mm porcelain slabs, this mechanical system uses undercut anchors drilled into the slab’s back face and fixed to a double-layer aluminum substructure. It enables concealed, secure installation with a clean, modern appearance.The system supports vertical and horizontal installation of large-format slabs up to 1620 × 3240 mm. Anchor placement is based on slab thickness, weight, and project requirements, with drilling performed on-site per supplier guidelines. Suitable for façades requiring high strength and flexibility, it allows precise alignment and adjustments during installation. A dry, adhesive-free method, it ensures long-term durability and structural safety.

Component Breakdown

  1. Structural Support Wall: Concrete, CMU, or framed substrate (not supplied)
  2. Waterproofing Layer: Protects wall assembly from moisture (not supplied)
  3. Thermal Insulation: Installed behind the substructure for energy efficiency (not supplied)
  4. Mechanical Anchors: Fix brackets and substructure to the support wall
  5. Thermal Break Pads: Prevent thermal bridging and galvanic reactions
  6.  Stainless Steel Self-Drilling Screws: Used to fix brackets, hanger, and aluminum profiles
  7. Aluminum Brackets (L-shaped): Define cavity depth and transfer structural loads
  8. Vertical Aluminum Profiles: L- and T-shaped profiles forming the primary structure
  9. Horizontal Aluminum Profiles: Support and integrate with the anchoring system
  10. Undercut Anchors: Inserted into pre-drilled holes on the slab back
  11. Porcelain Slabs: 12 mm or 20 mm thick slabs, up to 1620 x 3240 mm, with pre-drilled undercut holes for anchor insertion
